VAPORIZER FOR INTERNAL-COMBUSTION ENGINES.

W of Great Britain, residing at Spittlegate llron ll' orks, Grantham,Lincolnshire, Eng- "land, have invented new and useful Im provements inor Connected with Vaporizers for Internal-Combustion Engines, of whichthe following is a specification.

0 Our invention relates to improvements in vaporizers for internalcombustion engines of the kind described in the specifications of formerPatents Nos. 7146 and 15994 of 1890, the object of our invention beingto provide 5 simple means whereby the degree of com pression and theproportion and consequently the value of the heating surface of thevaporizer may be varied in order to render the latter capable of dealingetliciently 0 with fuels which differ widely in their physicalproperties. To this end, according to our invention, we form or providethe vaporizer with a recess, channel or the like, of any convenientshape in cross section, such as rectangular and in any convenientposition in the said vaporizer, but preferably across the bottom andcommunicating with the interior thereof. In conjunction with the channelwe provide a series of compression blocks which are so shaped that theyfit in the said channel and may be either solid or formed or providedwith gills or ribs for the purpose of increasing their heating surface.Furthermore, the said blocks may have their surface formed or arrangedso as to provide greater or less metallic contactwith the metal wall ofthe water-cooled porl'l(]1 of the 'aporizer. lVith this arrangement itwill be obvious that a compre on block can be selected which isparticularly adapted for the quality of fuel to be employed. Forexample, in the case of fuels requiring an extreme degree of heat forvaporizing purposes we may make use of a block having ribs or gills andpresenting a minimum of contact area with the body of the vaporizer.Again for fuel that requires a high degree of compression and acomparatively low degree of heat we may employ a block of maximum sizeand without ribs or gills, but with a maximum surface in metalliccontact with the water-cooled part of the vaporizer. This latter type ofblock will obviously give the greatest degree of compression, and at thesame time will be heated only to a comparatively low degreeSpecification of Letters Patent.

having regard to the fact that the heat generated is conducted away bythe watercooled part of the vaporizer. In practice a door or coverprovided at the outer end of the channel and preferably at the side ofthe vaporizer for the purpose of enabling the blocks to be introducedand removed with facility.

In the accompanying drawing :Figure 1 is a longitudinal section of avaporizer having our improvements applied thereto. Fig. 2 is atransverse section on the line 22 Fig. 1. Figs. 3 and 4 are respectivelya side view and a vertical section of a compression block with gills orribs arranged crosswise relatively to the axis of the vaporizer. Figs. 5and 6 are views similar to Figs. 3 and 4 respectively of a compressionblock with the ribs or gills longitudinal to the axis of the vaporizer.Figs. 7 and 8 are similar views of a compression block made in sections,and Figs. 9 and 10 are like views of a compression block made in onepiece. Fig. 11 is a sectional view showing the vaporizer attached to thecylinder of a gas engine.

Referring first to Figs. 1 and 2 a is the non-jacketed part of thevaporizer and b is the portion thereof which is provided with thewater-jacket 0, (Z being the flanged neck by means of which thevaporizer is bolted to the engine cylinder, not shown in the drawing. cis the channel, recess or the like which is here shown formed in thebot-tom of the water-cooled part 7) of the vaporizer, although it willbe understood that it can, if desired, be made in the hot part of thevaporizer, and f is the compression block which is inserted Within thesaid recess or channel 0. To enable the block to'bc introduced into, andwithdrawn from, the channel e the vaporizer is provided with adetachable door 9. As above described the reccss or channel 6 may be ofany convenient shape in cross section, such as rectangular asillustrated, and may occupy any suitable position within the vaporizer,although in practice we have found good results are obtained byarranging it across the bottom and communicating with the interiorthereof as in the example shown in the drawing. Furthermore, the block fmay vary in shape and design in order that the same vaporizer may beadapted to deal efficiently with fuels having different physicalproperties. A number of different designs of compression block are shownin Figs. 3 to 10.

The block shown in Figs. 3 and at is made in one piece and is providedwith gills h extending longitudinally along the block while that shownin Figs. 5 and 6 is similar but has gills 2' extending transverselyacros the blocks.

Figs. 7 and 8 show a block composed of a number of parts 7', jand'without gills, while Figs. 9 and 10 illustrate a block made in onepiece and without gills.

Having now fully described and ascertained our said invention and themanner in which it is to be performed, we declare that what we claim is7 1. In an internal combustion engine, the

combination with the cylinder, of a vapor-- izing chamber, a removablecompression block stationarily supported in said vaporizer, saidvaporizer having an aperture to facilitate the insertion and removal ofsaid block and a closure for said aperture separate from said block.

2. In an internal combustion engine, the combination with the cylinder,of a vaporizer connected therewith and provided with a recess forreceiving and retaining in stationary position a removable compressionblock, a removable compression block for engaging said recess, and meansfor holding said block removably therein.

In an internal combustion engine, the combination with a vaporizerprovided with a lateral aperture in its wall, a recess in line with saidaperture for receiving and retaining in stationary position a removableblock, a removable compression block fitting said recess, and adetachable closure for said aperture.

at. In an internal combustion engine, the combination with the cylinder,of a vaporizer communicating therewith having a portion thereof providedwith a water jacket and having a recess in its jacketed portion, and alateral aperture in the wall of the vaporizer in line with said recess,a removable compression block for engaging said recess, and a detachableclosure for said aperture.

5. In an internal combustion engine, the combination with a vaporizer,provided with a transversely disposed recess, and having a lateralaperture communicating therewith, of a removable compression blockfitting in said recess and a detachable closure for said aperture, saidblock being held for move ment by said closure and the walls of saidrecess.

6. In an internal combustion engine, the combination with a vaporizerprovided with a substantially cylindrical vaporizing chamher, and havinga recess extending transversely of the axis of the said chamber, beyondthe cylindrical portions thereof, and a removable compression blocklocated in said recess and having portions of its surface disposed inline with the cylindrical wall of the vaporizer.

7. In an internal combustion engine, the combination with a vaporizerprovided with a substantially cylindrical vaporizing cham ber, andhaving a recess extending transversely of the axis of the said chamberbeyond the cylindrical portions thereof, and a removable compressionblock located in said recess and having portions of its surface disposedin line with the cylindrical wall of the vaporizer and having projectingportions extending into the vaporizing chamber.

8. In an internal combustion engine, the combination with the vaporizerprovided with a recess to receive a compression block, of a removablecompression block adapted to be inserted in said recess, and providedwith gills.

9. In an internal combustion engine, the combination vith the vaporizerprovided with a recess to receive a compression block, of a plurality ofremovable compression blocks of different sizes and forms, and means forsecuring one of said blocks at a time in the va Jorizer, whereby bychanging said blocks the engine may be adapted to different fuels.
